I MPROVEMENT IN INSULATING RAILROAD-TRACKS.

Specification forming part of Letters Patent No. 209,215, dated October22, 1878; application filed August 3, 1878.

To all whom it may concern Be it known that I, LOUIS BASTET, ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Device for Insulating Railroad-Rails and M achinery, ofwhich the following is a specificatiOn:

Figure 1 is a transverse section of a railway embodying my improvements.Fig. 2 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to insulate the rails of railroads fromthe structure upon which they rest, so that the vibrations caused bypassing trains will-not be communicated to the supporting structure, soas to be diffused.

To effect the insulation of the ties upon which the rails rest Iinter-pose between the tie A and the trestle or girder B, upon which itrests, a compound block consisting of a layer, a, of stone, preferablyof the porous kind, and a layer, B, of thick felt. These are arrangedhorizontally, with the stone uppermost, and in contact with the underside of the tie. The tie is secured to the trestle by means of boltshaving lead washers under the nuts and heads.

By this device the continuity of the structure is broken, so thatvibrations cannot be communicated from the tie to the trestle or girder.

The rails are secured to the ties in the usual manner; but they are notsecured together by fish-plates.

Having thus described myinven tion, I claim as new and desire to secureby Letters Patent I 1. A sound-deadener between the ties and girders ofrailroads, formed of an upper stone layer, a, and a subjacent fcltlayer, b, asshown and described.

2. The combination of an insulator composed .of stone and felt with theties and tiesupports of a railway, substantially as herein shown anddescribed.

LOUIS lBASTET.
